Fast, Reliable Roof Replacement Across Lomita
Replacing a roof in Lomita means working with housing stock that’s older than most of the South Bay. The 1950s and 60s ranch homes off Lomita Boulevard and throughout 90717 were built well, but their original roofs are now 60-plus years old. When you call Gable Roof Repair, you get a crew that knows these houses, knows their failure patterns, and doesn’t lead with a replacement quote until the inspection justifies one. We’re brand-agnostic, repair-first, and we show up ready to scope the actual condition of your roof, not sell you something you don’t need. Call (866) 650-8319 to schedule a roof inspection or replacement estimate in Lomita.
Why Gable Roof Repair Is Lomita’s Preferred Roof Replacement Company
Lomita homeowners tend to be practical. Most have lived in the same ranch for decades, and they’ve seen enough contractor bids to know when someone’s padding the scope. Our reputation in Lomita comes from doing the opposite. We start every job with a standalone roof inspection, separated from any sales conversation, so you get a diagnosis before you get a number. Neil Drummond built Gable Roof Repair around that sequence: inspection first, recommendation second. It’s the reason a single Lomita address often calls us back when the detached garage or flat-roof add-on eventually needs work too.
Local response to Lomita is straightforward for us. Our crews are working South Bay roofs weekly, and we can typically route an estimate to a 90717 address within days of the call. We know the detached garages, the low-pitch hip roofs, the older plywood and 1x skip sheathing. That familiarity means fewer surprises for you after tear-off, and fewer change orders once the job starts.
Styles & brands we work with
Flat Roof Replacement in Lomita
Flat Roof Replacement in Lomita usually involves the detached garage, a mid-century add-on, or a covered patio that was enclosed decades ago. Many of these structures were built with a minimal slope and an old torch-down or rolled asphalt surface that’s now cracked, blistered, or ponding water at the low edge. In the South Bay marine layer, standing water doesn’t dry fast enough, and it works into the seams and flashing until the sheathing underneath starts to rot. A typical flat roof replacement in Lomita runs $8,000 to $16,000 depending on square footage, decking condition, and whether we’re adding new drainage or insulation.
Detached Garage Flat Roofs
Lomita’s ranch-era homes often came with detached garages, and those garages got the cheapest roof the builder could get away with. We see a lot of them now with failed seams and rusted edge metal. Replacing one is usually a one-day membrane job, but the scupper or drain location matters. If the old scupper drained toward the house, we re-route it or add a second drain so water moves away from the eave.
Coatings vs. Full Replacement on Flat Roofs
Not every flat roof needs to be torn off. Some can take a reinforced acrylic or silicone coating that buys five to ten years. We’ll tell you honestly which one applies. When the decking is sound and the membrane is just weathered, a coating can be the smarter spend.
Roof Installation in Lomita
Roof Installation in Lomita covers full tear-off and replacement of the main house roof, plus new construction or major re-roofs on additions. On a single-story ranch with a low-pitch gable or hip roof, we’re usually removing one or two layers of old 3-tab and inspecting the 1x skip sheathing underneath. A complete roof installation on a 1,200 to 1,800 square foot Lomita ranch generally runs $12,000 to $22,000 with architectural shingles, depending on decking repairs, pitch, and the number of penetrations. Low-slope sections may need peel-and-stick underlayment instead of standard felt, which adds a few hundred dollars but is the correct detail for wind-driven rain.
Architectural Shingle Installation
Most Lomita homeowners choose architectural shingles for their replacement because they hold up better to South Bay wind and rain than the 3-tab they’re replacing. They also hide the slight waves in older sheathing better than a thin 3-tab would. We install GAF, CertainTeed, and Owens Corning architectural lines regularly, and our crews nail to each manufacturer’s high-wind pattern rather than a generic one.
New Decking Over Existing Sheathing
Some Lomita homes still have 1x skip sheathing: spaced boards with gaps between them that modern shingles were never designed for. If your original sheathing is in good shape, we can overlay with plywood or OSB to create a solid nailing surface. If the boards show salt corrosion stains from years of onshore air and old leaks, we replace them section by section. That decision changes the quote, and we show you what we’re seeing before we write it.
Trusted Brands We Service in Lomita
We work with seven major shingle manufacturers, so the solution fits your roof rather than the other way around. That includes IKO, Atlas, and Tamko alongside GAF, CertainTeed, Owens Corning, and Boral. For Lomita homeowners, that matters in two ways. First, you get an honest comparison of materials at different price points instead of a single-brand pitch. Second, our crews understand the installation requirements, warranty terms, and known failure patterns across those product lines. Seven brands, one standard of installation. When you call (866) 650-8319, we’ll walk you through which lines make sense for a coastal-running South Bay ranch roof.

AfterCommon Roof Replacement Problems We See in Lomita Homes
- Salt-corroded flashing at chimneys and vents. Onshore air off the Palos Verdes and harbor area puts salt on every exposed metal surface. We routinely pull chimney flashing on Lomita homes and find it eaten through where the roof meets the brick or the vent curb.
- Hidden dry-rot at fascia edges on low-pitch roofs. Marine-layer damp sits along the eaves of low-slope ranches and never fully dries. The rot hides under the drip edge until tear-off exposes it, which is why an honest Lomita quote includes a decking repair allowance.
- Second-layer 3-tab over failing original shingles. Many Lomita homes got a cheap re-cover decades ago instead of a tear-off. Two layers trap heat and moisture, and the original layer’s granule loss means the roof sheds water poorly. We almost always recommend full tear-off to inspect what’s underneath.
- Flat-roof garages draining toward the house. Older scuppers and drains were often laid out without concern for where the water went. When the flat roof fails, the water runs back against the main house eave, and the damage is in two places at once.

FAQs About Roof Replacement in Lomita
Our Lomita ranch has a low-pitch roof, does that change the roof replacement scope?
Yes, and it’s the most common adjustment we make on Lomita quotes. Low-pitch roofs shed wind-driven rain poorly, so we reduce shingle exposure, switch to peel-and-stick underlayment on slopes below 4:12, and pay closer attention to eave and valley flashing. It adds cost compared to a steeper roof, but skipping it is how you get recurring leaks. Call (866) 650-8319 and we’ll measure your actual pitch before quoting.
Can you replace the shingles over the original 1x skip sheathing?
No, and we won’t. Modern shingles need a solid nailing surface, and the gaps in skip sheathing leave shingles unsupported. We overlay the existing sheathing with plywood or OSB once we’ve verified the boards are sound, or we replace damaged boards first. It’s a line item in our estimate, not a surprise after tear-off.
Why do Lomita roofs see so much flashing and fastener corrosion?
Salt-laden onshore air off the Palos Verdes and harbor area carries salt onto every metal roof component. Flashing, fasteners, and attic vents corrode years ahead of roofs in Redondo Beach or inland Torrance. When we replace a Lomita roof, we assume all exposed metal gets replaced unless the inspection shows otherwise.
How do you compare roof replacement bids for a Lomita home?
Look for whether the bid includes decking repair, whether it specifies underlayment type for low-slope sections, and whether it treats a detached garage or flat-roof add-on as a separate scope. If a bid has one line item for the entire property, it’s guessing. We itemize by roof system, because a Lomita ranch often has two or three distinct systems under one roof line.
Do architectural shingles hold up in South Bay wind and rain?
Yes, and they’re the product we recommend most often in Lomita. Architectural shingles resist wind uplift better than 3-tab, they handle the marine layer’s moisture cycling without curling, and manufacturer warranties typically run longer than 3-tab equivalents. Nailing pattern matters as much as the product, and our crews nail to each manufacturer’s high-wind specification. Call (866) 650-8319 for a quote with the specific shingle you’re interested in.
